Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589016, here are decompositions:

5 + 31589011 = 31589016
23 + 31588993 = 31589016
37 + 31588979 = 31589016
59 + 31588957 = 31589016
73 + 31588943 = 31589016
83 + 31588933 = 31589016
89 + 31588927 = 31589016
307 + 31588709 = 31589016

Showing the first eight; more decompositions exist.
